    SCIENCE, DEFLATEGATE AND THE NATIONAL FOOTBALL LEAGUE

    DeflateGate has erupted onto the National stage, and seems poised to stay there through Superbowl Sunday and beyond. It has been a fascinating, tortured soap opera that has vexed most of us and brought out the worst in some of us. What if this controversy can be resolved through a more reasoned process? What if it could provide a teachable moment for the country about how justice and fairness can be undermined by our collective ignorance of established science and fact, and how what we don't know can distort our beliefs and actions? It is with such high hopes that I share these thoughts with you about under-inflated footballs.


    INTRODUCTION

    To determine if the New England Patriots have violated NFL rules about ball inflation, the main question is, "Was the drop in ball pressure due to natural causes or tampering?" As Coach Belichick explained last Saturday, the best way to truly answer this question is to do an experiment. Before such an experiment, a scientist will need to form a testable hypothesis, a prediction, based on the facts of the situation and what is known about natural laws. In this case, the relevant physical law is the Ideal Gas Law (Pressure x Volume = n x R x Temperature) combined with the fact that friction generates heat.

    Check out this informative video which also explains the science behind the pressure-drop: https://www.youtube.com/watch?v=hf8oQ4rhR-A


    THE FOUR PHYSICAL PHASES OF DEFLATEGATE

    Knowing the conditions at the AFC Championship game and how the Patriot’s footballs were treated, it’s not hard to anticipate the result based on the four different physical phases the balls went through. The logical prediction is that ball pressure would drop significantly below the NFL minimum 12.5 psi. In fact, this is a certainty:

    1) Rubbing Phase - Before the AFC Championship game, Brady's balls were in the locker room, where the air temperature was likely 70-75 degrees. His balls were then rubbed vigorously for a substantial preparation period. The rubbing created heat from friction. The heat increased the air Temperature in the footballs above the indoor temperature. The warm air couldn't expand the footballs by much, so the Pressure would increase.

    2) Cooling Phase A - Brady's warmed balls were given to referee Walt Anderson, who was asked to set the pressure at 12.5 psi. The warmed balls stayed in the official's locker room for over 2 hours and gradually cooled back to the indoor temperature. This initial drop in Temperature would result in a corresponding drop in Pressure (approx 1 psi per Coach Belichick).

    3) Cooling Phase B - 10 minutes before kickoff, the balls were taken by NFL staff to the sideline. The temperature was approximately 50 degrees, but would have been lower on surfaces exposed to rain and wind-chill. Over the course of the first half, Brady's wet balls would have cooled to below 50 degrees. This second drop in ball Temperature would result in a further drop in ball Pressure (psi).

    4) Stretching Phase - In addition, the leather of a wet football stretches, increasing the Volume inside it. Increased ball Volume would cause a third drop in ball Pressure (psi). Did you see the condition of the balls? Several pictures show them dripping wet and soaked through in the hands of the players and referees. The leather would have stretched - how much would have to be determined by experiment.

    Taken together, these physical and climate factors would definitely drop the pressure in the footballs to substantially below the 12.5 psi set, per NFL protocol, by officials 2 hours pregame. This is not a possibility, it is a certainty.

    Just like when you hold a solid object in your hand then let it go, it will fall according to physical laws (gravity), so it is that whenever a referee in their locker room inflates a warmed ball to the lower limit of 12.5 psi, then takes it out into cold, wet, windy weather, that ball will be underinflated 100% of the time. There is no question that this has happened countless times in late season, cold weather games throughout the history of the National Football League. Asterisks all around for everybody, especially the Packers!


    A MATTER OF DEGREE

    Aside from the certainty of cold weather pressure drop, the real question we are left with is, "How much does it drop?" This will be answered not by rifling through the team's email, text messages and surveillance video, but rather by an experiment. Hence Coach Belichick's usual common sense in taking the opportunity to do just this before the team left Foxborough. Until someone else performs and documents the definitive experiment (several amateur scientists have posted attempts on YouTube), we should all take him at his word that ball pressure would have dropped enough, without any tampering, to account for what was observed by the referees during the recent AFC championship game.


    THE CATCH-22

    It should be pointed out that an NFL football team could have avoided football deflation below the league minimum 12.5 psi in very cold weather by checking the ball pressure on the sideline during the game and pumping more air into them (increasing the “n” in the Ideal Gas Law). However, this would violate NFL rules by tampering with the balls. Teams have been placed by the NFL in an untenable situation where they’re “damned if you do and damned if you don’t”… and double-dog-damned if they happen to be the New England Patriots.


    THE BLIND LEADING THE BLIND

    During this fascinating, frustrating, all-consuming week of DeflateGate, some might wonder how could so many intelligent, highly paid NFL executives and officials have established such a flawed rule, a rule that appear ignorant of the fact that cold weather drops ball Pressure.

    The DeflateGate "scandal" rages on because so many remain mystified by the inexplicable deflation of footballs in a cold, wet game. The science needed to dispel this mystery is not hard to grasp. In fact, the ideal gas law was formulated back in 1834, and is taught in high school physics class. Tragically, many journalists and commentators lack this knowledge and have plunged ahead recklessly with false accusations and little curiosity about the basic facts of the matter. They think that for the pressure to drop significantly, someone must have let air out of the Patriots balls. They just know it. Emboldened by ignorance and sinister suspicion, they have proclaimed the Patriots must have cheated by intentionally let air out of the balls by tampering with them. We wonder why so many media pundits have been so blind to their ignorance.

    Answers to these questions come from the other important scientific field at play in DeflateGate: Cognitive and Social Psychology. Discussion of this is complex and goes way beyond the issue of football pressure, but is extremely relevant to the media and society at large. If you are interested, please look up "Cognitive Bias" and "The Dunning-Kruger effect: Why The Incompetent Don’t Know They’re Incompetent".

    The science of cognitive bias is necessary to help us to understand how overconfident NFL officials established unworkable inflation rules. It also helps us to better understand why so many pundits have failed to appreciate the reasons for football deflation in a cold wet game yet have gone on to lob accusations of ball tampering with great confidence and righteous indignation (and a few tears).


    THE SOLUTION

    While the science of human cognition and its limitations is probably powerless to eliminate the mass hysteria of DeflateGate, Obama birthers or Climate change luddites, high school physics can reliably keep NFL footballs properly inflated during games in any kind of weather. It could, in some small way, embody the way an enlightened society can solve problems in a rational, effective manner. Like most true solutions, the fix for NFL balls is simple, cost effective and elegant. Here it is:

    1) Keep the current process of the teams giving their game balls to the officials 2-3 hours before kick-off. The officials have time to inspect the balls and allow time to correct any concerns.
    2) At least 90 minutes before kick-off, the officials place the balls in breathable tamper proof bags or other containers, seal the containers with tamper-proof fasteners, and take them down to the field. This will allow the air inside the footballs to equilibrate to the climactic conditions (i.e. temperature) on the field.
    3) The bags should be placed in plain sight of both teams, fans and officials in the center of the field. In any case, they must not be left near sideline heaters or fans.
    4) The outside of the containers should be reflective White in color. (If the containers were black or other dark color and left in the sun, they will heat up the balls and prevent equilibration.
    5) Whether to keep the balls dry from any rain will have to be determined.
    6) The officials will break open the tamper-proof seals 10-20 minutes before kickoff, remove the balls, and adjust air pressure to NFL specifications.
    7) Officials should be allowed to check and readjust ball pressures at half-time or other times during the game.

    Problem solved.


    SUMMARY

    This unfortunate outcome is the direct result of the NFL executives, lawyers and business owners with inadequate knowledge of basic high-school physics, who have established irrational rules for pregame football inflation. Robert Kraft’s indignation is certainly justified, but should be tempered by the realization that he joined so many others in implementing them. While apparently competent to manage business and legal matters, one wonders about the competency of NFL officials to handle all the other important matters facing the unprecedented sport of American football (like the science of concussions and head injuries).

    DeflateGate is not about who said what to who, about how long it takes a young man to relieve himself before heading to the sideline, about whether a coach or player is popular or likeable, about whether anyone should have felt a drop in football pressure drop by squeezing the ball, or about whether deflation makes it easier or harder to hold, throw or catch a football. At least, this is not what it should be about. No, this controversy is simply about the pressure-drop in footballs during a cold, wet game. To determine whether or not pressure would have naturally dropped without tampering, the NFL needs a few scientists, not a team of lawyers on a witch hunt in need of a conspiracy. Most importantly, there is a simple, science-based process that NFL referees can easily follow to prevent similar problems in the future. It involves leaving the balls in sealed white bags at midfield for 90 minutes then adjusting ball pressure 15 minutes before kick-off.

    You, on Marshawn Lynch. "His defiant, repetitive responses in interviews are given under the guise he doesn't want people to notice him. Instead, it is a creative way for getting everyone to pay attention."

    I'm going to explain to you why you are wrong about his interviews, and I'll even be nicer than some of the other posters.

    Firstly, he's been avoiding the media for a long time, and for most of that time, the media didn't care. At the end of the 2013 season, Seattle came into the national spotlight, and the national media wanted to talk to one of the star players of the surging Seahawks. As per usual, he was uncomfortable, and didn't want to talk. His avoidance of the media before he was in the spotlight could hardly qualify as "attention-seeking," so it hardly seems reasonable to re-qualify his current avoidance of the media as such. He hasn't changed his behavior: the only thing that has changed is the national media's demand for his attention.

    As to his recent one-word interviews: it's the "if I do it badly enough, they won't ask me to do it anymore" approach. There are two conflicting conditions for Lynch. A) He doesn't like talking to the media, and B) he is required to be available for the media or else get fined. The only way to satisfy both A and B is to create a situation in which he is available, but the media doesn't want to talk to him. The only way to do that is to make it clear that he won't be providing "substance" in his post-game interviews, with the hope that reporters will lose interest. Now, you could be right, and he could be a terrible interviewee just for the press, but given his consistent history of avoiding the press, I think that my explanation is more logical and more likely.

    Anyway, the "Marshawn not talking" story has generated far more media than anything he'd be likely to say. He clearly doesn't want to open up. Would we really prefer phoned in generic answers from him just to hear him talk? Shame on the media for hypocritically demanding more of him while simultaneously keeping him a headline fixture by milking this narrative for over a year.

    sad you can't go an article without bashing lynch. how are you allowed to write articles for this site you are a fucking child

  • Rah Diggah posted 96 days ago

    Rah Diggah

    Damnit, Ericka!

    WHY WON'T YOU LISTEN? Marshawn is trying to help you!

    You've got to blot that sand out your cookie, before your weeping vajay-jay gives us all a rash.

    At first? I thought it was cute how you couldn't help but keep your personal vitriol out of your press. Now? It's just sad, if not the kind of "ha-ha, what a fag", laugh at you kind of funny.

    Brass tax? Fuck you. You don't get to tell us what to love and what to hate.

    I completely agree with Don Carnage and, apparently, everyone else that has commented on that POS article and your personal attacks on too very talented Seahawk players. Why you feel it's necessary to personally attack Marshawn is beyond me. Nothing makes you happy...Sherman talks too much, Marshawn doesn't talk enough. The only reason Lynch is getting so much attention is because idiots like you in the media won't stop talking about it and writing about it. Last time I read ANY articles on this website. You are bully and hack. You basically just suck and I have a hard time believing anyone would call this journalism. ASS HAT

    Don Carnage

    Hey Eric, You're going to be getting a lot of these hate messages for your article and I hope you don't lose sight of why your position is stupid AND inflammatory.

    First, In one article you complain about Sherman talking too much, and then go on to complain about Lynch not talking at all. Pick one fight and stick to it. Unlike you, they aren't making their living by vomiting up easily consumed word garbage in web-page space conscious portions.

    Second, remove your personal issues with Lynch from your articles and stick to the football. The dude is playing the game in a way few have in recent years, and recently he's been doing it while also taking 2-3 drives off per game to go to the sideline and VOMIT from all the back pain he's playing through. Marshawn Lynch has the heart of a lion, he gives everything for his teammates and the game, and he doesn't need the bile media hacks like you give him just because he wont also give you some throw away quotes each week to fill space in your garbage articles. Try doing some analysis instead.

    That's all. Feel free to continue to be a click baiting troll, it seems to be industry standard amongst you hacks anymore.

    I was surprised when I read what you wrote about Marshawn on the power rankings. Then I clicked on your profile, and saw a picture of you. Just from your face I can see you are a fat, unattractive, hypocritical piece of human garbage. Please, don't be a complete asshole when Bleacher has no one better to do the power rankings so they ask some fat white guy that breaks a sweat every time he opens his mountain dew can.

    Marshawn Lynch is a Punk?? Really? I don't mean to be rude, but that's really scraping the bottom of the barrel when it comes to classy journalism, or journalism period.. besides (just to come down to your level) why don't you just walk up to Lynch and tell him that face to face.. Really, you can have your opinions of people, but "them's fighten" words son.. and that's one you would be better off hiding behind your key board..(like you're doing)
